AI Ability since v2.0.0

# create\_chain\_link

Add a chain link — Add a source→target edge to a chain.

Add a source→target edge to a chain. Rejected if it would create a cycle across any chain. Registered as the WordPress Ability `flowsystems-webhook-actions/create_chain_link`, so external AI tools (Claude Code, Cursor) can call it over MCP or REST with a scoped API token.

/ Plan step shape

```
{ "ability": "create_chain_link", "input": { "chain_id": …, "source_webhook_id": …, "target_webhook_id": … } }
```

/ Scope & confirmation

Minimum API-token scope for external (MCP/REST) callers: `full`. Runs without a confirmation pause (the overall plan is still user-approved before execution starts).

/ Input fields

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| chain\_id | param | integer | yes |  |
| source\_webhook\_id | param | integer | yes |  |
| target\_webhook\_id | param | integer | yes |  |

/ Examples
